OpenRoads Seed File, Tasks, Tools and Settings

OpenRoads work is more like Microstation than traditional MX. Most commands are given through Task lists and many MicroStation commands are used to manipulate the created features. New seed files, Tasks, Tools and Settings have been or will be set up to work effectively in OpenRoads.

OpenRoads Seed DGN File

A typical MX DGN has 3 models in it; a 2D Default model, a 3D Default-3D model and an MX model. Work should be done in the Default model unless otherwise stated. All MX Models and strings will be displayed in the MX model.

The Default model has the Default-3D model (attached with live nesting) which has the MX model attached to it. So you can see all the information in the dgn when the Default Model is open. Individual Windows can view different models of the 3D information even when in the Default 2D model. Use the View Group > Multi-Model Views to display both a 2D and a 3D view at the same time.

Previously, there was a single seed file for OpenRoads drawings - NHDOTMX_seed_i_3d+2d.dgn. That file is now called nhseed-or-intf.dgn ("or" = OpenRoads, "intf" =
International Feet). All future projects should be set up with U.S. Survey Foot drawings using the seed file nhseed-or-ussf.dgn ("ussf" = US Survey Feet) when
working in OpenRoads. Design work on US Survey Foot drawings should be done with InRoads while work done in International Foot drawings should be done with MX. There are other seed files for special purposes. For a complete list and details on how to set the seed file for a project, see NHDOT Seed Files.

Suggested Civil Tools and Settings

Suggest having the CAD menu across the top. If the MX menu is currently displayed, select CAD Menu from the File menu.

Check the Geographic Coordinate system from Tools > Geographic > Select Geographic Coordinate System. It should be set to <None> in all models of the DGN. Hit on the last icon Delete Geographic Coordinate System if you have one defined.

Geographic Coordinate System

Check Working Units from Settings > Design File > Working Units

Design File Settings

Also verify Station Format as ss+ss in the Civil Formatting
Category of the Design File Settings.

Resource Cache - Open Workspace > Preferences > Operation to increase the resource
cache: to 4096, or some other multiple of 1024 if you have more RAM.
